Welcome to the forum.  *welcome*

With regard to a lot to learn, we all started there. As a '51 A7, it wouldn't be a "Golden Flash," but, possibly, a "Star Twin" or just "A7." No matter, looking forward to seeing a lot of pictures of getting her up to running condition. If you think the engine is good right now, that's great, but you should probably take it apart to inspect the whole thing and, very importantly, clean the sludge trap (lots here on that when you use the search tool). If you do that, it may stay good.

 Hi DB.   I reckon a time seized Oil Pump  and a blocked pick up pipe trumps just about everything else mechanically. Then considering the magneto.......

Great to have you on the site, we love photo's!
Don't listen to all these gloom and doom merchants. These bikes are over 70 years old so one that's been off the road does need a good going over, (yes always worth flushing the sludge trap on any BSA or trumpet twin ). But they are simple bikes and if put together with a bit of care are amazingly robust. While I don't presently have a 500 on the road, I've ridden a mates star twin and that is such a sweetie, smooth as. No wonder these bikes earnt the Maudes trophy (worth reading about) for their ISDT exploits. My experience is mainly with the 650's but am building a 500 racer, thats how much faith I have in these motors.
Don't hesitate to ask, don't believe everything you hear, but on the whole you'll get useful support and direction.

This is a blocked sludge trap, (on another model of motorcycle) . Oil is supposed to pass through here on the way to the big ends 🤪
